IMPROVEMENT IN ADJUSTABLE*LAOCK-COUPLINGS FOR VEHICLES.

The Schedule referred to in these Letters Patent and makingparl: of the sama.

I, GEORGE G. BUneEss, of Grafton, in theconnty ot' Lorain and State of Ohio, have invented certain Improvements in Adjustable Lock-Coupling for yVehicles, ot' which the following is a specihcation.

The n atnre of my improvement consists in the con# vplexit) of removing and replacing bolts and nuts.

Reference being had to the drawing hereto annexed and to the letters marked thereon, which make a part otthis` specification, in which- Figure 1 is a perspective view of theparts together, and

Figure 2 of them separate. A. is aclip-piece, which is made fast to the axle or other proper part of a vehicle.

G is a strap or 1od, which is secured ou the back end of the pole or thill.

D is a round hook, made or formed on or i'om the end of the strap C, and nearly at right angle.

' ll is a retaining block ot' anydesired shape, and is made or formed on the side and end of the hook D. A B is a socket in the clip-piece A, and is made in shape and size to correspond with that of the cud of the hook I) and block E, and is made large enough to admit them to pass into and through thesocket B when the clip A and strap C stand iu the relation to cach other as shown at iig. 2.

There are two sets of said clips and straps used, inv

order to connect the end of each thill, (see fig. 1,) or one'at either end of the cross-piece of a pole, in' the usual manner.

After the hooks D D are passed into the sockets B B, the pole or thills are dropped down to a horizontal position for use, when the blocks E E on the end of the hooks D D rest against thesocket-side ot' the clip A, thereby efeetnally lockingthe hooks into 'their sockets, as shown at fig. 1.

I am aware that various devices have been used for connecting poles and thills to vehicles, and that some ot' them are patented, in which there should bel nothing anticipated except from the exact combination set forth.

Believing that I am as justly entitled to a patent fora new combination for a similar purpose as thoseA that have prccededme, I hereby disclaim the .pintles l, spur G, recess E, and spring D, as shown and described in the patent of George T. leansall, April 30, 1867; but I claim- In combination with the socket B, the hook D, and retaining-block E, when constructed and arranged to operate together, in the manner and 'for the purpose substantially as shown and set foi-th.
